A comparison between the actual gasoline engine and actual diesel engine is to be made. Assume the heat added is the same. Check all that apply. Group of answer choices Because the diesel engine has a lower compression ratio the thermal efficiency will be higher because less work is required to compress the air. Because the diesel engine can run a higher compression ratio the thermal efficiency will be higher. Because the diesel engine has a higher efficiency, it reponds quickly to rapid accelerations and in-city driving conditions compared to a gasoline engine. The diesel engine compresses only air on the compression stroke and is not knock limited so the compression ratio can be much higher The gasoline engine is knock limited and the compression ratio will be lower than the diesel engine The gasoline engine compresses only air on the compression stroke and is not knock limited so the compression ratio can be much higher
